U-turns are a turning issue, maybe they're legal in one place, maybe they aren't in another these things should be mapped some how but this is getting off track. > In general, the more important question than whether or not you can U-turn > is whether or not you can cross the center line in order to make a left > (right if you drive on the other side) turn.

Why are bridges different? Usually because bridges narrow things to make it cheaper to cross a river etc, however my point still stands a way is a physical thing, if there is only one physical thing then that's all that should be mapped and lanes should be tagged independently of the way. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
